Have you ever updated your Drupal site only to suddenly have errors?

If you use Drupal regularly, this will happen to you at some point. However, one of the good things about using Drupal is there are so many other users that someone else may well have found and solved the error.

One common way to solve an error is with a patch. A patch changes the code on your site, but only by editing a file rather than providing a complete update.

Many of the available instructions for applying patches ask you to use an application called Git and to use command line instructions. These instructions can be intimidating, so we're going to show you how non-coders can safely and effectively apply patches.
